He is day-to-day. … Brian Matusz had to be brought to the emergency room Tuesday night after suffering an allergic reaction. It was taken care of and he is able to pitch now.

Additions

Andrew Cashner re-injured his strained right latissimus dorsi muscle and has been shut down for the rest of the year. The injury had been nagging, but he felt sharp pain during his latest start. He already missed 59 days because of the earlier injury.

Dellin Betances was placed on the 60-day DL with right shoulder inflammation. He was already on the minor-league DL but was brought up and placed on the 60-day DL to clear the roster space so the Yankees can activate Brett Gardner. Betances is expected to be ready for the start of next year.

Subtractions

Andy Pettitte was activated from the 60-day DL yesterday and promptly shut down the Blue Jays for five innings. He missed 83 days because of the fractured ankle, which is within the normal range of fracture healing.

Travis Hafner was activated from the 15-day DL after missing 44 days with disc-related issues in his low back. Disc injuries don’t heal on their own, but they can become less painful. Because of this limited healing capacity, there is a chance Hafner’s back will flare up again this season. The Indians are unlikely to use him every day, but he should get a fair amount of playing time.
